Always double-check an LLM, particularly when it's just a quick(er) search away:

Specifically: JSON is built-in, logging is available. There's no multiprocessing (it is designed for a micro, after-all - and note that thread is available on some ports), no built-in XML lib.

Be sure to check micropython-lib, the MicroPython Awesome List and mim for others.
